HIV-related sensory neuropathy ( HIV-SN) mainly contains the HIV infection-related distal sensory polyneuropa-thy (DSP) and antiretroviral toxic neuropathies (ATN).HIV-DSP is associated with proinflammatory cytokines , chemokines, ros and which is induced by gp 120;and HIV-ATN may be related to mitochondrial toxicity which is induced by the application of anti retroviral drugs, such as ddC, and similar as the molecular mechanism of HIV-DSP, this means that the current conventional method for the treatment of neuropathic pain in AIDS may further aggravate the neuropathic pain of the patient .Therefore, developing the study on the neurochemical and pharmacological mechanisms of HIV-related neuropathic pain will provide novel targets for the new effective drugs .

Objective : To investigate the effect of aluminum exposure on expression of miR-497-5p, wingless murine breast cancer virus integration site family member 3a (Wnt3a), β-catenin protein, glycogen synthase kinase-3β (GSK-3β) protein and tau protein in rat adrenal pheochromocytoma PC12 cells, so as to provide insight into unraveling the mechanisms underlying aluminum exposure-induced abnormal phosphorylation of tau protein. Methods: PC12 cells were exposed to Al(mal)3 at concentrations of 0, 100, 200, 400 μmol/L for 24 h. The viability of PC12 cells was measured using cell counting kit-8 (CCK-8) assay. The relative expression of miR-497-5p and Wnt3a was detected using a real-time fluorescent quantitative PCR (RT-qPCR) assay, and the expression of Wnt3a, β-catenin, GSK-3β, P-GSK-3β (Ser9), tau and p-tau (Ser396) proteins were determined using Western blotting. Results : The viability of PC12 cells appeared a tendency towards a decline with the increase of aluminum dose (Ftrend=323.473, P=0.001). RT-qPCR assay detected that the relative miR-497-5p expression appeared a tendency towards a rise with the increase of aluminum dose (Ftrend=14.888, P=0.031), and the relative Wnt3a expression appeared a tendency towards a decline with the increase of aluminum dose (Ftrend=165.934, P<0.001). The miR-497-5p expression negatively correlated with the relative Wnt3a expression (r=-0.693, P=0.012). The expression of Wnt3a (Ftrend=357.656, P=0.001), β-catenin (Ftrend=208.750, P=0.001) and p-GSK-3β (Ser9) proteins (Ftrend=512.583, P<0.001) appeared a tendency towards a decline with the increase of aluminum dose, and the expression of GSK-3β (Ftrend=39.965, P<0.001), tau (Ftrend=277.929, P=0.006) and p-tau (Ser396) proteins (Ftrend=96.247, P=0.002) appeared a tendency towards a rise with the increase of aluminum dose. Conclusion Up-regulation of miR-497-5p and GSK-3β expression and down-regulation of Wnt3a and β-catenin expression may be a mechanism underlying aluminum exposure-induced abnormal phosphorylation of tau protein.
